What Is Grain Free Dog Food?

The best grain free dog food brands will not have any wheat, corn, barley, oats, rye, rice, or soy. During World War II, manufacturers commonly used these ingredients as inexpensive filler in pet food. Consequently, this was not optimal for Fido’s nutrition or weight.

Think about what your dog naturally craves. Has Fido ever attacked a wheat stalk? Probably not. But he may have stalked a rabbit or a squirrel. Similarly, he more likely begs for your bacon than your oatmeal.

The best grain free dog foods focus more on a dog’s ancestral diet. As a result, they will list protein sources as the first ingredient or ingredients. Manufacturers list components by weight, so the higher an ingredient is listed, the more of it the food contains.

You may be looking at your current brand and think, “Well, it lists chicken as the main ingredient.” Read the rest of the ingredients. Is the same food listed in multiple ways?

Some manufacturers may show a protein as the first source. However, they also list corn, corn bran, and corn gluten in the ingredients. However, all are still corn. As a result, when you add them, they may outweigh the protein source. Therefore, it is essential to read all the ingredients.

The best grain free dog food brands, however, are not necessarily low carb. Dogs need carbohydrates for energy and a balanced diet. For that reason, most of the best grain free dog food brands may use sweet potatoes, legumes, or peas to provide needed carbohydrates.

Benefits of Using the Best Grain Free Dog Food

As the low-carb trend with humans gained favor, so did the idea of feeding our pets the best grain free dog food we can. After all, we want them to be as healthy as possible.

While only one percent of dogs have a grain allergy, many can benefit from eating the best grain free dog food you can give them.

As discussed earlier, a grain free diet is more in line with what dogs naturally eat.

Also, the best grain free dog food brands are formulated using higher quality ingredients. They use whole protein sources such as beef, chicken, lamb, turkey, salmon, and eggs. Obviously, this is preferable to the byproducts used in some other brands of dog food.

The first thing to remember is that any time you change your dog’s diet, you should do so gradually. Unless your dog has an iron stomach, he might have some adverse reactions to a sudden kibble change.

PetMD encourages owners to introduce new food to your dog gradually over the course of five days.

On Day 1, mix 20 percent of the best grain free dog food you choose with your dog’s current food. Each day after, increase the amount of the new food by 20 percent, while decreasing the old food by the same amount. Finally, by day 5, your dog should get a bowl of just the new kibble.

Basically, the daily breakdown looks like this:
